IMPROVEMENT IN CORN-PLANTERS.

Specification forming part of Letters Patent No. 205,890, dated July 9,1878; application filed June 12, 1878.

To all whom it may concern:

Be it known that I, D. E. MOORE, of Irescott, in the county of Adams andState of Iowa, have invented certain new and useful Improvements in Corn-Planters; and I do hereby declare the following to be 'a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it pertains to make and use it, referencebeing had to the accompanying drawings, which form part of thisspecification.

My invention relates to an improvement in corn-planters; and it consistsin the cheap-an d simple arrangement and combination of parts whereby anefficient, durable, and easily-operated planter is produced, as will bemore fully described hereinafter.

Figure 1 represents a vertical section of my invention. Fig. 2 is avertical cross-section, taken at right angles to Fig. 1.

a represents a rectangular frame, of any desired construction, which issupported at its rear end by the driving-wheels b, and at its front oneby the furrow-openers c, as shown. Passing up through the rear part ofthe frame, within easy reach of the drivers seat d, is the lever e,which is pivoted near its lower end to a hanging part of the frame a,and which has the two levers f pivoted to it, one on each side of itscenter of motion.

When the leverc is moved sidewise the two levers f are forced outward inopposite directions, for the purpose of forcing the clutches h in gearwith the wheels, so as to cause the axle 'i to revolve with them. Theseclutches may be of any suitable construction, and are connected to therods j, which have their rear ends securely, but loosely, held in therear end of the frame, and to these rods the outer ends of the leversare fastened.

lVhen it is not desired that the seeding mechanism shall operate, theclutches are moved inward out of contact with the wheels,

-when the shaft remains motionless.

At the center of the shaft is formed the crank k, to which is connectedthe connecting-rod l, which has its front end slotted for a considerabledistance and passed over the rod or bar m, which connects the two leversn together. In this slot 0, in the front end of the rod 1, is placed asliding block, g, which is joined to the hand-lever p by theconnectingrods 1'.

By moving this sliding block up against the bars m the full movement ofthe crank back and forth is transmitted to the bar, so as to move thelevers n to their full extent; but in proportion as the block is movedbackward in the slot, away from the bar, there is a loss of motion, andthe bar is moved less and less. After the clutches have been thrown ingear with the wheels the seeding mechanism may be thrown in and out gearat any moment, independently of the axle by simply moving the block inthe slot.

To the lower ends of the levers a, which are pivoted upon the sides ofthe seed-boxes, are secured the feed-slides s, which are shaped so as todescribe an arc of a circle, and move back and forth in similarly-shapedgrooves under the bottom of the seed-boxes, and over the tops of thegrain-tubes t.

Each one of the seed-boxes is made semicircular in shape on its inside,and is provided with a partition, 1*, in its center, and each side ofthe box has an opening through it for the seed to fall throughcorresponding to the two holes in the seed-slides.

To each of the furrow-openers 0, just in advance of where it is joinedto the tubes t, are pivoted the fenders to, which are adjustable up anddown at their front ends, through the slots 3 for the purpose of causingthe openers to run shallow or deep. These fenders serve to clear awaythe clods, corn-stalks, and other such substances as would have atendency to fall back into the furrow on top of the grain.

Having thus described my invention, I claim- The combination of thecranked axle, slotted connecting-rod I, sliding block q, and a lever foroperating it, with the bar m, levers n, and the seed-slidessubstantially as shown.

In testimony that l claim the foregoing I have hereunto set my hand this6th day of June, 1878.

D. E. MOORE.
